I'm giving this half a star more than I gave the first movie. As a horror film in its own rite, it's competently made, although somewhat predictable as it follows most of the traditional haunted house film tropes. But it is better than the first one in that it's a more cohesive film, with such corrections as how the background "monster" actually does play a part in the story, whereas in the first film Annabelle was shoehorned in but had nothing to do with the main story and served only as a distraction.

Ultimately, the reason I can't rate this film higher is because it's about the Warrens, who were a couple of charlatans that took advantage of vulnerable and desperate people. While this is touched on briefly, it's done more in the context of people who don't believe them are all mean and unsympathetic.

Again, it's a competently made horror film that's better than its predecessor, if a little predictable, but don't look at it as being based on a true story. Take it with a massive grain of salt.
